How to redirect to url instead of error message? "Direct assignment to the forward side of a many-to-many set is prohibited."
I wish if the object exists in the database the user would just be redirected to "watchlist" instead I get the error "Direct assignment to the forward side of a many-to-many set is prohibited. Use addedauction.set () instead.". def addtowatchlist(request, auctionurl): Watchlist.objects.get_or_create(owner=request.user, addedauction=auctionurl) if Watchlist.objects.get_or_create(owner=request.user, addedauction=auctionurl) == False: return redirect("watchlist") return redirect("watchlist") -
How can I do this same thing using DRF OrderingFilter?
I am hoping to order a model by a DateTimeField using the DRF OrderingFilter. I am able to do this manually but not with the DRF backend. I have the following ModelViewSet: class DropTemplateViewSet(viewsets.ModelViewSet): serializer_class = DropTemplateSerializer filter_backends = [DjangoFilterBackend] filterset_fields = ["status"] def get_queryset(self): qs = DropTemplate.objects.annotate(start_time=F("collectiontemplates__visible_start_time")).filter(author__id=self.kwargs["author_pk"]).distinct("id") if "ordering" in self.request.query_params: return drop_templates.order_by("author_droptemplate.id", f"{self.request.query_params['ordering']}") else: return drop_templates I am using the distinct("id") because this Annotated QuerySet contains DropTemplates in the response. How can I achieve the same thing with the OrderingFilter? When I attempt to do this with the following ModelViewSet: class DropTemplateViewSet(viewsets.ModelViewSet): serializer_class = DropTemplateSerializer filter_backends = [DjangoFilterBackend, OrderingFilter] filterset_fields = ["status"] ordering_fields = ["title", "start_time"] ordering = ["start_time"] def get_queryset(self): return DropTemplate.objects.annotate(start_time=F("collectiontemplates__visible_start_time")).filter(publisher__id=self.kwargs["publisher_pk"]).distinct("id") I get this error: SELECT DISTINCT ON expressions must match initial ORDER BY expressions LINE 1: SELECT COUNT(*) FROM (SELECT DISTINCT ON ("publisher_droptem... ^ ) -

Selenium webdriver.Remote() can't click on elements
Situation I'm using the Selenium Remote webdriver to do my tests on a Django project. I have several Docker containers, which is why I needed to use the Remote driver. Problem Thing is, the Selenium and Django project containers are connected properly and I am able to perform tests, but whenever I try the click() method on any element, I get the error Element <...> could not be scrolled into view However, by searching around I found out that doing self.driver.execute_script("arguments[0].click();", element) instead does work. I've read somewhere that it might be a problem that some part of the website is not loaded yet when Selenium attempts to click(), but that still doesn't tell me what to do. Any ideas? -

Data Analytics website using Django Python
I want to create a python project that uses mysql for database, django for the webframe. The website will contain a bunch of graphs fetched via different REST APIs and will create plots for the given data. I will be using docker to install all the dependencies (cython, numpy, pandas, matplotlib etc.) . Matplotlib will create the plots to be forwarded to the django website. The website will automatically update itself periodically as more data comes in over time (gathers new data from the APIs once a week maybe). To access the data the user will have to login with user credentials(login and password). Only a handful of people will be able to access the website so it is not dedicated to have a lot of traffic. I will be using Bluehost to host my django website in the end. I have never worked with web frames before would this be a hard task to accomplish. Are there easier ways to implement this? Open to any suggestions. Any problems I might face whilst developing ? -

how to handle authentication in django for multiple apps and functionality

Getting the original language or original text of date in Excel file
I have a Django application where I give users a Excel file for them to give me dates, i ask them to give me the date in DD/MM/YYYY format (the one used in Latin America) The problem is that if the language of the Excel file is in English, it uses the MM/DD/YYYY format. So for example if they write 01/05/2022, when i open the file in my application i receive 05/01/2022. So I want to know if there is a way to get the original language of the excel file, for me to put some conditions inside my application, or if i can get the original raw text of the file. I can't change the format that the application uses (because I receive excel files that are mainly in the spanish language) or ask my clients to write the dates in a different format, or ask them to change the language of the file. I am open for other type of solutions too. -
Django: How to show a PointField in a map from a html template?
I have a Django class in my models.py, similar to the following: class MyClass(Model): .... description = TextField() location = PointField() In my views.py: template = loader.get_template('my_class.html') context = { 'my_class': MyClass.objects.filter(....), } return HttpResponse(template.render(context, request)) Finally, from my my_class.html template I can easily print each of the properties in my MyClass object: {{ my_class.description }} But {{ my_class.location}} just prints something like POINT (-13.716858926262476 50.42083468131796). Is there an easy way to show the point in an OpenStreetMap map? (Similar to the map in the admin page when using OSMGeoAdmin) Do I need to create a form for that if this template is read-only? (I dont need to edit any of the fields) (I'm using Django 3.2 in case that is important) -

I have values a,b,c,d if (a,b) also (c,d) positive value will not allowed, i wrote the code this way but do not know why is not checking the validation. I am working on django forms.py for i in range(count): a = int(self.data.get(f'runtime_set-{i}-a') or 0) b = int(self.data.get(f'runtime_set-{i}-b') or 0) c = int(self.data.get(f'runtime_set-{i}-c') or 0) d = int(self.data.get(f'runtime_set-{i}-d') or 0) if a ==b==c==d==0: continue if (a + b) > 0 and (c + d) > 0: raise ValidationError( "When A ,B is postive then positive C,D value is not allowed ") -
sitemap.xml <loc>https://example.com/?val1=1&val2=1</loc>
i did follow Django Sitemap Tutorial to create a sitemap.xml with GenericSitemap. That work good for Blog, But i need to add more links like: https://example.com/?author=NAME&taq=TAQ&Category=category and add link only if there is result for all 3 parameters author taq category models.py class Main_Category(models.Model): name = models.CharField(max_length=200, verbose_name=_("Main_Category")) class Tag(models.Model): name = models.CharField(max_length=200, verbose_name=_("Tag")) class Category(models.Model): name = models.CharField(max_length=200, verbose_name=_("Category")) Main_Category = models.ForeignKey(Main_Category, on_delete=models.CASCADE, null=True, blank=True) class Blog(models.Model): title = models.CharField() author = models.ForeignKey('users.CustomUser', on_delete=models.CASCADE) main_Category = models.ForeignKey(Main_Category, on_delete=models.CASCADE) taq = models.ForeignKey(Tag, on_delete=models.CASCADE, null=True, blank=True)
